Preventive Maintenance Keeps Your HVAC System Up and Running

Winter isn’t far off in Chicagoland, and if you haven’t already scheduled preventive maintenance on your HVAC system, now is the time to do it. An annual tune-up will ensure your system operates efficiently for the duration of the heating season, and will also provide these benefits:

While tune-up checklists vary among contractors, a reputable HVAC company will perform a comprehensive tune-up, including these essential points:

  • Lubricate all moving parts of the system to prevent friction
  • Tighten connections, including gas and electrical
  • Test the burner combustion and gas pressure
  • Inspect for potential carbon monoxide leaks
  • Clean and inspect the blower assembly and measure the airflow
  • Measure the voltage and current on the motor
  • Inspect the terminals and wiring for corrosion and other damage
  • Inspect your ductwork for obstructions and loosened joints
  • Test the controls of the system to ensure it cycles properly

After your tune-up, there are several things you should do to ensure your system maintains its efficiency for the duration of the winter:

  • Inspect your furnace filter every month. When it’s clogged with dust, replace it with a good-quality, clean air filter. A dirty filter will impede the airflow to and from your system, requiring it to work overtime to keep your home comfortable.
  • Seal air leaks around windows, doors, and service entrances to keep warm air in and cold air out so your furnace doesn’t have to work harder to compensate.
  • Reverse the direction of your ceiling fan blades so that they distribute the warm air near the ceiling to the lower section of the room, keeping you warmer at lower thermostat settings.
  • Insulate your ductwork that runs through unconditioned areas, such as the attic or crawl space to keep the air inside them warm and reduce the load on your system.
